ISAAC H. RANDALL, OF BOSTON, MASSACHUSETTS.

STREET-CLEARING MACHINE.

SPECIFICATION forming part of Letters Patent No. 354,224, dated December14, 1836,

Application filed February 19, 1836. Serial No. 192,601. (No modcLl Toall whom it may concern.-

Be it known that i, Isaac H. RANDALL, a citizen of the United States,residing at Boston, in the county of Suffolk and State of biassachusetts, have invented a new and useful Street-Clearing Machine, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to a machine especially designed for removing snowfrom street-railway tracks, embodying devices for loading, dumping,plowing, leveling, and sweeping snow. The machine is also suitable forclearing other places than the railwaytracks, and

u to operate on other material than snow, as

sand or gravel.

My invention consists in the devices and combinations hereinafter setforth, and speciti cally pointed out in the claims.

In the drawings, (three sheets.) Figure l is a plan, Fig. 2 a view ofone side, and Fig. 3 a front end view, of a machine embodying myinvention. Fig. 4 is a view of the same side of the machine after thesheer has been removed and the forward end of the box or body has beenlowered into position for loading. Fig. 5 is a view of the same side ofthe machine, the sheer having been removed and the forward end of thebox or body raised into position for dumping. Fig. 6 is a view of theother side, and Fig. 7 a view of the rear end, of the machine. Figs. 6and 7 show the machine on wheels, while the other figures show themachine on runners, the devices embodied in the machine being of suchconstruction that wheels or runners may be employed, as circumstancesmay require.

On the cross-pieces or axles A and B is located the frame-work,consisting mainly and substantially of longitudinal rails O and D,uprights E and F, and braces G and H. At the front end, on the rails Oand D, is a platform, I, and a suitable dasher, J. On the cross-piece oraxle A is pivoted the box or body K, having the bottom a and sides I) Z)open at the forward end and provided with a tailboard, a, pivoted at d.Supported by the uprights E andF is a shaft, e, on which are fixed drumsf f. I prefer to have also fixed on the shaft 6, at one end, a gear, 9,and to have a pinion, h, to engage therewith, the pinion being 011 ashaft in suitable bearings, and having a crank, i, thereon. A rope, j,or chain, extends from each drum to a side of the box or body near itsforward end, where the end of the rope is fastened. Thus, by turning thecrank the forward end of the box or body may be raised or lowered. Thetail-board may be locked, when closed, by means of a shaft, k, bearingan arm, Z, which may, be swung up against the board, and an arm, m, tothe outer end of which is connected a rod, a, extending forward, so asto be conveniently reached from the platform I. Near this end the rod amay be formed to engage with a pin or catch, 0, thus holding the arm Zagainst the tail-board.

Diagonally across the machine, under and extending beyond each side ofthe box or body, is a sheer, L, having suitable frame or braces, M andN, which may be suspended and held by links or chains 1;. This sheer maytake the form of a scraper, as shown in Figs. 1, 2, and 3, when one endthereof may have an extension, 0, pivoted'at q, so as to be raisedvertically when required; or it may be a brush, as illustrated in Figs.6 and 7. The sheer is suspended near one end by a link, 0', connectingthe same with a lever, P, and near the other end by a link, 5,connecting the same with a lever, Q. The lever P is pivoted at t, andmay be held at any angle by a pin in a guide, a. The lever Q, is pivotedat o, and may be held at any angle by a pin in a guide, w. Each of theselevers may be located so as to be operated by a person on the platformI, as shown.

is accompanied with much labor and expense,

which it is the purpose of my invention to greatly decrease. \Vhen thesnowis quite deep, the sheer may be removed, the box or body lowered atthe forward end, as shown in Fig. 4, by means of the ropes winding offthe drums, so that as the machine is drawn along the bottom of the boxor body will he slid under the snow and the box or body be filled. Thebox or body then being raised to a level position, the load may behauled to the dumping-ground, and dumped by raising the forward end, asshown in Fig. 5, by means of the ropes winding on the drums and byreleasing the tailboard. Thus the machine becomes a self-loader Ice andunloader, so that shoveling by hand may be dispensed with. If the snowis only of suffioient depth to require a scraper or brush, either may bequickly put in place and the work of clearing go on by means of one andthe same machine, by which, being on the ground, the work may be muchmore readily performed than if another machine were required.

Though removing snow from street-railway tracks is the work for which Ifind an immediate demand for my machine, yet it is suit able forremoving snow from streets where there are no railway-tracks and fromother places, and also for removing other substances, as sand or gravel.

I claim as my invention- 4 1. A machine provided with a box or bodysupported by four wheels or runners and pivoted at the rear cross-pieceor axle, A, and means for lowering the forward end of said box or bodybetween the front wheels or runners, whereby on the forward movement ofthe machine said box or body may be loaded, substantially as set forth.

2. In combination with a box or body supported by four wheels or runnersand pivoted at the rear cross-piece or axle, a drum or drums,

ff, shaft therefor, and a rope or chain or ropes or chains, j, forlowering the forward end of the box or body between the wheels orrunners or raising the same, substantially as and for the purposes setforth.

3. In combination with cross-pieces or axles A and B, longitudinal railsO and D on said cross-pieces or axles, a box or body, K, pivoted on therear cross-piece or axle, A, substantially as and for the purposesspecified.

4. The combination of cross-pieces or axles A and B, frame 0 D E F,platform I, and box or body K, pivoted at the rear cross-piece or axle,A, substantially as and for the purposes set forth.

5. The combination of the cross'pieces or axles A and B, a body or boxopen at the forward end and pivoted on the rear cross-piece or axle, A,and provided with a pivoted tailboard, e,with means for locking thetail-board, as the rod n and the shaft 70, provided with arms Z and m,substantially as and for the purposes specified.
